Concrete Wall Form Removable Bolt Tie Sleeve

ABSTRACT

The Concrete Wall Form Removable Bolt Tie Sleeve is a process developed that utilizes a flexible polyolefin plastic sleeve to improve the efficiency of the current concrete wall forming process. The bolt tie is placed inside the flexible polyolefin plastic sleeve before inserted into the wall form. The sleeve saves the installer time by no prior greasing of the bolt tie, no returning on site to “turn” the bolt tie, and no cleaning of the bolt tie after it has been removed. The flexible polyolefin plastic allows the sleeve to not adhere to the concrete, allowing the bolt tie and the flexible polyolefin plastic sleeve to be easily removed after the concrete has dried.

BACKGROUND OF INVENTION

The invention of the Concrete Wall Form Removable Bolt Tie Sleeve wasdeveloped to offer a more efficient process than what is currentlypracticed today. Below is a step-by-step explanation currently of howBolt Ties known as “She-Bolts”, “Taper-Ties”, and “Threaded Rods” areutilized within the concrete wall form process today.

Definition

“She-Bolt”—Heavy Duty reusable bolt for medium to heavy concreteconstruction of wall forms. These bolts come in various sizes andlengths, and are 100% reusable. These bolts are threaded at each end andgenerally smooth on the center that is exposed to the concrete inbetween the interior of each wall form.

“Threaded Rod”—Heavy Duty reusable bolt for light, medium to heavyconcrete construction of wall forms. These bolts come in various sizesand lengths, and are 100% reusable. These bolts have a continuous threadthat runs the entire span of the bolt.

“Taper-Tie”—Heavy Duty reusable bolt for medium to heavy concreteconstruction of wall forms. These bolts come in various sizes andlengths, and are 100% reusable. These bolts are threaded at each end andhave a smooth tapered center that is larger at one end and smaller atthe other end, making this bolt a one way inserting and one way outremoving from the wall form.

1. Temporary walls are erected one on each side to create the form forthe concrete to be poured into.

2. Bolt Ties known as “She-Bolts”, “Tapper Ties”, and “Threaded Rods”are coated with a thick layer of grease where the bolt will make contactwith the concrete within the center of the wall form. This allows forthe Bolt Tie to be removed after the concrete has dried and the wall has“set-up” since these bolts are 100% reusable.

3. The Bolt Ties are inserted through both of the walls then securedwith a plate washer and a wing nut on both sides of each exterior wallform to give the walls adequate strength to hold the immense weight ofthe concrete prior to it drying and setting up.

4. After the concrete has been poured into the wall form, and it beginsto set up hours later, a technician must return and give every insertedbolt through the wall a “Turn” breaking it lose to make certain theconcrete is not setting to the Bolt Tie. If this step of the process isnot performed, the Bolt Ties can become stuck inside the wall, causingthe technician several labor hours to cut or remove with force with theaid of a torch heating the bolt.

5. Finally the wall forms and Bolt Ties are ready for removal since theconcrete wall is now dry and “set-up”. Once the bolts have been removedthey must be inspected and cleaned thoroughly prior to being reused inthe next wall form.

There are currently other forms of Bolt Ties being utilized in concretewall forms such as “Snap Ties” and “Expendable Plastic Tubes & Cones”.Both of these systems are single use products that will be abandoned inthe concrete wall since they will adhere and become fully set to theconcrete once it is dry. This adds more expense to the concrete wall, asthey are single use expensive products, and is a wasteful use ofmaterials. This is also compounded with the rise of Steel and Plasticprices.

BRIEF SUMMARY OF THE INVENTION

The Concrete Wall Form Removable Bolt Tie Sleeve was developed tostreamline the existing process that was described within the inventionsbackground. The Removable Bolt Tie Sleeve consists of a plastic calledPolyolefin. This specific type of plastic was found to have a specialcharacteristic in the fact that it does not adhere to concrete as itdries. In the step-by-step process described in the inventionsbackground instead of coating the bolt tie with a thick layer of grease,which is a messy process that requires time and labor, instead simplyinsert the bolt tie through the removable bolt tie sleeve prior toinserting to the wall form. This saves jobsite labor, time, andmaterials. As an addition time and labor savings the technician nolonger needs to remain onsite to turn the bolts as the concrete beginsto dry and set. The removable bolt tie sleeve makes this step in theprocess obsolete due to the polyolefin flexible plastic sleeve. The bolttie can be removed from the wall with a light tap to the bolt tie, andthen removed by hand. Once the bolt tie is removed you can also removethe flexible sleeve from the concrete wall by hand as well by simplypulling it out. Both the bolt tie and the sleeve is removed with easesaving the technician labor, time, and materials. The bolt tie is alsoremoved clean and free of any debris or greasy coatings and ready forthe next use.

DETAILED DESCRIPTION OF THE INVENTION Concrete Wall Form Removable BoltTie Sleeve

FIG. 1

This complete overview of all the assembled components in the concretewall form process starts with 100 the erected walls. These walls arewhat make the concrete form, giving the wet liquid concrete a containerto be poured into. In order for these walls 100 to not be pushed apartfrom the immense weight of the liquid concrete a bolt tie 102 usuallyreferred to as a She Bolt, Treaded Rod, or Tapper Tie is insertedthrough both walls and then fastened with a wing nut on each side of theexterior wall giving the walls the strength to hold the form together.Prior to the bolt tie 102 to be inserted through the walls it is firstinserted through the removable bolt tie sleeve 101. The sleeve is cut tolength long enough to be visible through each exterior side of the wall103 extending out to cover the bolt tie 102. Once the assembly is fullyconstructed as shown in Figure one the concrete can now be poured intothe center or interior of the wall forms 100. As the liquid concrete ispoured into the interior of the walls 100 the bolt tie 102 is fullyprotected by the removable bolt tie sleeve 101. The bolt tie sleeve 101is made of a Flexible Polyolefin Plastic. It has been discovered thatthis type of plastic does not adhere to concrete. Allowing the bolt tie102 to be easily removed once the concrete has “Set-up” or dried.Another benefit is that the installer does NOT need to remain onsite togive the bolt tie a “Turn” with a wrench to keep the bolt from adheringto the concrete. Once the entire assembly is installed and the concretehas been poured, the installer does not need to return until it is timeto remove the form once the concrete has dried. Now that the concretehas dried the bolt ties 102 can be removed with ease due to the flexiblepolyolefin plastic removable bolt tie sleeve 101. The walls 100 can beremoved, and since the removable bolt tie sleeve 101 was cut to lengthlong enough to extend to the exterior of the walls 103 the entireremovable bolt tie sleeve 101 can be removed easily by hand as well.

FIG. 2

This complete figure shows how the bolt tie 105 also known as aShe-Bolt, Threaded Rod, and Tapper Tie is inserted into the removablebolt tie sleeve 104 prior to being inserted into the wall forms. TheConcrete Wall Form Removable Bolt Tie Sleeve 104 is made of a FlexiblePolyolefin Plastic that has been discovered to not adhere to concrete asconcrete “Sets-up” or dries.

FIG. 3

This figure shows the bolt tie 106 inserted fully into the Concrete WallForm Removable Bolt Tie Sleeve 107 ready to be installed into the wallform. The sleeve 107 fits snug around the bolt tie 106 but still has theability to be slid by hand. The Concrete Wall Form Removable Bolt TieSleeve 107 comes in all different lengths and diameter sizes to fit allof the different sizes of bolt ties 106.

FIG. 4

Figure four is a complete exploded view of the assembly process. Thebolt tie 108 is first inserted into the Concrete Wall Form RemovableBolt Tie Sleeve 109, and then it is finally inserted into both sides ofthe wall form 110. Once the assembly process is complete, the liquidconcrete is ready to be poured into the center of the wall forms 110.After the concrete has “Set-up” or dried, the assembly can bedisassembled by removing the bolt tie 108, and removing the wall form110, and finally removing the Concrete Wall Form Removable Bolt TieSleeve 109, due to the fact that the sleeve is made from a flexiblepolyolefin plastic that does not adhere to concrete.

1. The Concrete Wall Form Removable Bolt Tie Sleeve is a component of asystem process to construct a concrete wall, the system processcomprising of: a bolt tie to be inserted into the Concrete Wall FormRemovable Bolt Tie Sleeve. This now sleeved bolt tie is to be insertedinto wall forms giving the walls adequate strength to hold the wallforms together from the immense weight of the concrete in its liquidstate. As the concrete dries the Concrete Wall Form Removable Bolt TieSleeve does not adhere to the concrete as it dries because thiscomponent is made of a Flexible Polyolefin Plastic. After the concretehas dried the bolt tie can be easily removed due to the Concrete WallForm Removable Bolt Tie Sleeve. The wall forms can now be removed, andfinally the Concrete Wall Form Removable Bolt Tie Sleeve can be removedfrom the concrete wall easily by hand due to the Flexible PolyolefinPlastic that does not adhere to concrete.
